To all 'whom t may concern.'

Bie it known that I, Louis DAMARIN Granos, a citizen of the United States,resid ing at Hackensack, in the county of Bergen and State of New Jersey, have invented certain newV useful Improvements in Dump-Cars; and; I do declarez the following to be a fulh clear,l and exact description of the invention, `such as, will enable others skilled in the art. to which it appertains to ina-,lie anduse the saine, reference being had to, the accompanying drawings, and to the letters. and figures of reference marked thereon, which form a part of this specification.

My invention relates to dump cars, and has for its, object, to provide a latch construction in which the latch in one position will lool; the, car-,body in itsk upright rel-ation,and also. in which the latch in another position will'secure the body in a. partially tilted relation; also in which, when the latch has, been, shifted` from its. lockingposition in changing the body from its upright to its tilted position, a part of the car body will engage and lift the latch so as to move it from the path of movement of the engaging part; also in which in moying the body from its, dumping to .upright prosition a part. of the car body will engage the latch and swing it soI as yto permit the part to passA by it, and furthermore will be engaged by said part so aS: to, swing it from its vlocking position in orden that the body ymay assume. its lupright position and be locked therein by thelatch. Ithasl furthermore forfits object totvprovide iinproyed features of consti-notion in other parts vof the car to simplify.y and increase their eiiiciency.

T0 the' accomplishment of the foregoing and such other objects as may hereinafter appear-the invention consists in the features hereinafter described and then soughty to be clearly dened by the claims, reference being had to the accompanying drawings forming a part hereof, and in which:

Figure l. an end View of e dump Caf embodying the invention; l g i Fig. 2 is a horizontal section thereof on the line 2-2 of Fig. l;

Fig. 3 is an end view showing the carbody in a partially tilted position;

Fig. 4 is a similar view showing the body in its dumping position;

Fig. 5 is a fragmentary view, partly in section, showing the latch in position to lock the body in its upright position;

Fig; 6, similar view showing the latch in position to secure the car-body in a par-- tially tilted position.

In the drawings the numeral l designates the car-frame which may be of any approved type Of. construction, and 2 the car-body which in general features is of the ordinary type.

Upon the frame, at opposite ends, are the bowed or arch-shaped standards 3, preferably formed of angle-bars,a1idj braced by the uprights al. To the standards are bolted, or otherwise attached, upright extensions 5V and 6, preferably of channel iron, and to opposite ends of the car-body yare bolted, or otherwise attached, rocker-shoes 7, which rest upon the arched standards 3 so as to roch thereon between the upright extensions 5 6. The rocker-shoes preferably have depending side flanges 8 to fit along the side edges of the standards, and also by preference provided with studs 9 on their under faces so as to enterslots 10 in the top of' the` standards to prevent sliding of the shoes in rocking on the standards.V

To the upright extensions 6, one of which is at one side of the car-body at one end thereof and the other at the opposite side at the other end, are pivotally supported the latches 11. As both are formed and oper- Vate alike, the description of one will anvS110@ when the body is in its upright POS- tion as shown in Figs. 1 and 5 so as to prevent the body from rocking, or in other words loch it in its upright positlOll.. In

dumping the body, the latch on the side where the operator is standing is swung on its pivot into a position with its free end overhanging the rocking-shoe, and the body then tilted away from the operator. In the movement of the car-body the end of the rocker-shoe will strike a shoulder 15 formed on the under face 0f the latch for the purpose and kick the latch back into its first or normal hanging position at the outer side of the upright extension 6, and when the car-body is rocked back to its upright position the end of the rocker-shoe will strike the dog projecting through the slot yin the weboi the extension and swing the latch outwardly so that the shoe may pass to its normal position when the latch will swing by gravity so asto bring the dog above the end of the shoe and lock the carbody.

It' it is desired to tilt and hold the carbody in a partially tilted position short of the full dumping position they body will be tilted to the position indicated in Figs and 6 so that a pin 1G provided on the underside of the latch will enter a socket 17 formed in the end of the rocker-shoe and thus lock the body `against either forward or backward movement.

If for any reason or cause the latchbe thrown or left in the overhanging position indicated in Fig. 4 when the car-body has been put in its dumping position, then on moving the body back to its upright position the end of the rocker-shoe will strike the inclined face 18 of the `latch and by the impact throw the latch back to its normal hanging position.`shown` in Figs. 1 and. It ywill thus be observed that the latch is automatically thrown or swung into the positions mentioned by impact of `the rocker shoe therewith in ythe movements of the car-body. It will also be observed that it is only necessary to manually manipulate the latch at one end of the car when it is desired to unlock the car-body and tilt the body away from the operator whether it is to be dumped in one directionor another.

The numeral 19 designates a lever for the brake mechanism.

The construction described is composed of few parts which are simple and eiiicient to discharge the functions specified for them.

I have illustrated and described with particularity the preferred details of construe tion but it is to be understood that alterations may be made without departingfrom the essential features as expressed in the appended claims.

Having described my invention and set forth its objects what I claim is:

l. A dump-car comprising a tiltable carbody, a rocker-shoe attached to the body, a

Copies of chily patent may be obtained for support aifording a bearing for the rockern shoe, upright extensions between which the rocker-shoe may oscillate, a gravitating locking latch pivoted at one end to oneof the upright extensions, the latch consisting of an elongated `arm formed at its pivoted end with a dog so disposed that when the arm is in its normal downward and outwardly inclined position the dog will overlie the rockershoe to secure the car-body in an upright position, and means for sustaining the arm in an upwardlyT and inwardly inclined position in the path of the rocker-shoe so as to be engaged by the shoe in the movement oi' the car-body to throw the arm into its normal inclined locking position.

2. A. dump-car comprising a tiltable carbody, a rocker-shoe attached to the body, a support affording a bearing for the rockershoe, upright extensions between which the rocker-shoe may oscillate, and a gravitating locking latch pivoted at one end to one of the upright extensions, the latch consisting oil an arm formed at itsV pivoted end with a dog so disposed that when the arm is iniits normal downward and outwardly inclined position the dog will` overlie the rocker-shoe to secure the car-body in its upright position, the opposite Jface of the arm being formed yto interlock with the rocker-shoe to hold the car-body in a tilted position when the arm is swung ,to an upward` and inwardly inclined position, the upright extension `to which the latch is pivoted being formed with a slot to receive the dog of the latch, there being a web across the upper end of the slot to afford a rest for the latch in its elevated position.

3. A dump-car comprising a tiltable carbody, a rocker-shoe attached to the body, a support aifording a bearing for the rockerm shoe, upright extensions from the support between which the rocker-shoe may rock, and

a pivoted latch supported by one of'said ex` tensions, the rocker-shoe being formed with a socket andthe `latch with a pin to enter the socket to secure the car-body in a tilted position.

In testimony whereof I aiiix my signature in presence of two witnesses.
